STOP DEVICE FOR BRAIDIiNG-MAGHINES.

To all whomv it may concern: I

Beit known that I, SIMON W. WABDWELL, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode- Island, have invented cer-' tain new and useful Improvements in Stop. Devices for Braidin -Machines, of which the following is aspeci cation.

M '"vention-relates to stopdevices for \brai: ing'machines and its purpose is to more effectively arrest the machine 5 action after withdrawal of driving action and insure such relation of the brake devices to the drivingfdevic es that there shall be no brake 1 5 eifect before the driving action ceasesand no driving action before the brakes are entirely withdrawn, the contrary causingundue wear v and deterioration.

The construct-ion and mode of operation of myinvention are fully disclosed in the "1 following specification and accompanying drawingswhich respectively represent: Figure- Lia part sectional view of the braidlng machine showing the driving mechanism, in

which is preferably onthe same shaft 6 with said pulleyFig. 1. The clutch 4 is secured to the shaft, while the pulley 5 can run freely thereon when disengaged from the clutch.

On the outer turret 2 are mounted the yarn supplies of the lower tier (one of which is shown'at 7 Fig'. 3) with their tension controlling devices and appertaining'elements. In the outer turret 2 is'also formed a raceway Bfor the runner 9 of each ofthe carriers for the supplies of the upper tier, one

of'which with a;carrier 10 is shown at 11. These carriersrevolve about the axis of the braiding machine, represented by the broken Specification of Letters Patent.

lis fulcrumed on the stud 22.

the same stud is a lever'23 which carries av f latch 24, which in turn engages, by 'a shoulder 25 at its'lowerportion, the detent line 12, in a direction opposite to that of the outer turret 2,;their movement' being con.- cordant with that of the .inner turret 13 which also is driven by the gear 5, as shown in Fig. 1. On the inner turret 13 a head14.

ret are preferably'mounted on ball bearings,

16 and 17 respectively, the/supporting ball races being in the frame 18 of the machine.

Rotation'of thegear 5- obviously "secures concurrent rotation of the'two turrets in opposite direction and revolution in opposite 7 direction of the upper and lower tiers of yarn supplies.

' a The clutch 4 preferablyof the'friction type and is controlled inposition by the yoke 19 on the arm 20. .The latter is con nected with the controlling handle 21 which i Mounted on I pin 26Figs. 7 and 8. The detent pin '26 is driveninto an overhanging portion 18 of the frame 18, see Fig. 2. The latch is held :in position to engage the detent pin 26 by the spring 2' ?,'s uitably anchored, asfor'ezg ample, to the projection 28. The lever 231s connected to move with the controlling handle 21 by a pin 29 mounted in said handle, but has a limited movement, independent ofthe controlling'handle because I the'aperture 79 in it, through which the pin 29 passes, is larger than the pin. The pin 29 further serves as an abutment to limit the action of the latch 24 which has a proj ection 30 to encounter the pin. The specific purpose of this arrangement is actually to maintain the latch 24 in operative engagement with the controllinghandle 21, sothat the latch may be moved independently of the lever 23,011 which it is mounted.

The machine is started manually by moving thefcontrolling handle 21 inthe direction of the arrow'A. This, through the arm 20 engages the'pulley 3 with its'clutch and through the pin 29 shifts the lever 23 to enspring 31 which is anchored to the frame 18 by a pin or other rojection18 and acting on the controlling andle 21 through the pin 29 withdraws and withholds the clutch 4 from the pulls 3. The same action is secured automatlcall through the following means. On a shou der 32 of the frame 18 is a ring 33 connected with the latch 24,

' through a projection 34 preferably a block rsecured to the ring. This block has an inen aging the clutch 4 from itspulley clined or. wedge surface 35 corresponding with a similar surface 36 on the latch 24. It has also a substantially radial surface 37 which engages a corresponding shoulder 38 on the latch 24, in line with but above the shoulder 25. When the rin 33 is moved in the direction of the arrow the end of the latch 24 is, through coaction of the surfaces 35 and 36, wedge d or forced radially away,

from the ring and out of engagement with its detent pin 26. Thereupon, the lever 23 is moved by the spring 31,, carrying with it thecontrolling handle 21, and thereby dis-' 'pulseof the spring, to the particular yarn tension required; If a very soft braidingis t isto be observed that the lower detent shoulder 25' of the latch 24 is slight and has but little engagement with its pm 26, while the upper shoulder 38 is of substantial proportions and bearing on thesurface 37 of 1 nied'by a movement of the ring to a'definite' the controlling handle 21, or by the block 34, .so that a movement of the latch 24 sufficient to disengage its pin 26 is not enough to disenga e the block 34, and thereforemovement o the latch 24 in the direction of the arrow B will be accompaextent whenever the latch is operated for purposes to be explained later.

whether the latch 24 be disengaged from its detent pin man'ually'throu gh operation of movement of the ring 33 eventhough slight, a complete movement of the -r1ng 33 is insured through its, prescribed range of action. The

- block 34 has another shoulder 76 which is v sfiectively. The ring 33 is moved through o' posed to. a corresponding shoulder 77 on t e latch 24. When the controlling handle 21 is moved manually to start the machine, positive movement of the ring 33 is insured through engagement of the latch 24 and the block 34 by their shoulders 77; and 76 res instrumentality of levers, one'of which 3.9 is shown in *Fig. 3, fulcrumed on the 'stand 40 which is secured .to the rin The lower end of this lever is forked an straddles the projection 41, Fig. 9. -Movement of the lever 39 acts with a prying. effect tomove the ring 33 and effect the action upon v the bracket, an

' tion that the feeler 46 is In short,

volves with its yarn supply about the machine axis 12, engagement will be made with .the latch 24 and clutch 4 above described. Such movement of the lever '39 occursautomatically upon breakage, exhaustion or undue slacking of a yarn from any of the lower supplies, as follows: The loweryarnw; is rendered through a guide eye 42 to the braiding. This uide eye is mounted in a flexible arm 43 w ich b its resiliency maintains the yarn taut un er variations of tension due to said yarn passing over and un--' 5 der the upperyarn sup has 11. The'arm 7 '43 is secured to a rock s aft .44 at the bottom end of which is a crank 45. 'From the cranka rod or feeler 46 extends throughthe-bearing 47 towa-rdthe lever 39 and is projected toward said lever by the spring 48, Fig. 14. The said spring is anchored to a lever 49 mounted, preferably in the hub 50 of the tension bracket on which thesupply 7 is mounted. The outer extremity of the lever en ages the detent teeth 81 of d by varying the location of the lever in these teeth the power-of'the spring 48 can be varied. Under proper tension of the yarn or, the ide arm 43" and with it the crank 45 are old in such posi- A withheldfrom en'- gaging the lever 39. Adjustment of the spring 48 accommodates the action of the feeler 46' under imdesired the spring 48 can be reduced in tension to such extent that a sli ht yarn ten sion serves to withhold the ro 46 from aco tive engagement with the lever 39. On the other hand, the tension of the spring48'can be so increased that only a very strong yarn, under heav tension, will sufiice to'hold the feeler 46 such engagement. Should 1 the yarn in any case become unduly slack,

or exhausted or should it break, the feeler 46 will be released and, p'ro'ected by the. spring 48 to such positlon t at, as it re the lever 39, and the rin 33 will be moved to, act upon the clutch mec anism as described. Stopping of the machine is similarly efi'ect-f 1 ed from theffup er 'tier of yarn 'supplies.' The outer turret ias a series of rockers, one. of which is shown at 51, Fig. 3. At the. ner. end of this rocker isa curved arm"52,

having on its under side'a distinct shoulder "53, Fig. g 10.' At the outer end, of the rocks-5,1 ,is Jan" arm .54 from the extremityiofwhich depends a finger 55, Fig. i

p 11;. Onfthisfingei" is a shoulder made byrcin gllon a ring-5'6, and between this, shoulder and the ,bearing through which the feelerpaisses is-fa compression s r'rn 57 which forces theifin er 55 upwar T e la-tteris in such position A that if depressed it engages the lever 39 in j the same manner as does the feeler46 controlled by yarn :rfrom the lower supply.

This finger with its rocker is mounted on the outer turret and acts as an intermediary between the lever 39 and the carriers 10. Such intermediation is essential because the carriers run in a direction opposite to that of the lower supplies which go with the outer turret, and the stopping agencies of both the upper and lower tier of supplies must act inythe same direction on the lever 39 inasmuch as only motion of this lever in one direction will serve to actuate the clutch and brake mechanism.

The rocker 51 is actuated by a feel'er ,58 which is one arm of a rocker 59 mounted in suitable hearings on the deck 60 of the carrier 11, as is more clearly shown in Figs. 12 and 13. On a crank 61 of this rocker is a detector 62 which extends upward between the sides of the arched standard 63. In

these sides are threadways 64 through which,

1 the yarn 3 passes, engaging the hooked upper end 65 of the detector 62. The detector tends downward under influence of the spring 66 which engages the arm 67 at the opposite end of the rocker 59 from the feel er 58 and, like the corresponding spring 48of the bottom tier, is anchored to a swinging arm 68 which can be engaged with any one of a series of graduated notches 69. The tension of the upper yarn y upholds the detector 62 against the reaction of the spring 66, and in case the tension relaxes unduly, or the yarn breaks or becomes exhausted from the supply, then the detector yields to the spring and the feeler 58 is pro ected to a posltion where, b the travel of the carrier 11, it encounters the curved upper edge of the arm 52 of the rocker 51 turning the latter and forcing the finger 55 to engage and move the lever 39 in the same manner as does the feeler 46 before described. The two tiers of supplies are so related that in their revolution they reach corresponding positions in their respective orbits, when approaching one of the levels 39, so that depression of the finger 55 will occur at a time when it will encounter and act upon the lever 39. To further insure such encounter and action, the arm 52 is elongated so that when engaged by the feeler 58, such engagement is continued to maintain the finger 55 depressed. Should the machine be turned backward, either through accident or for anypurpose, the feeler 58, if in the path of the arm 52, encounters the shoulder 53 thereof and is rocked back by it, so as to wipe over the arm 52 without damage. The actions thus described as ensuing from an improper delivery of the under yarn a: and the upper yarn y or either of them, effects only a suspension or withdrawal of the driving power applied to the machine for its operation. To be effective as a stopping device and adequately control the machine under such circumstances it is essential that means be provided to overcome the momentum acquired by the rapidly movin parts and quickly arrest their motion. T is 1s accomplished by the ring 33, through the agency of the superposed rin 70 which fits the annulus 71 of th main rame, and is prevent ed from turning by pins, one of which 72, shown in Fig. 3, extends from the shoulder 32 up through the ring-33. The latter has elongated openings, one shown at 73, see Fig. 5, through which the pin 72 extends, admitting a movement of the ring 33 suflicient for the clutching and unclutchlng action already described. On the mug 33 are wedges 74 which engage corresponding wedge surfaces 75 on the brake ring 70, which is indicated by the sectional view, Fig. 6. These are so disposed that when the ring 33 turns in the direction reverse of the arrow B (Fig. 2) to unclutch the machine from its driver, the brake ring 70 is raised. The upper edge of the brakering 70 is formed preferablywith a bevel or taper 70 which meets a corresponding bevel 70" on the outer turret, when raised, and not only lifts the turret from its ball bearing, but opposes its rotation with an intensity dependent on the inclination of the bevel and upon the weight of the turret and the parts whichit sust ains. their coacting surfaces 75 is such that when the machine is started, the wedges are first fully withdrawn from the brakering 70 and then the pulley 3 engaged with its clutch 4; and vice versa, when the machine is stopped, either manually or automatically, it is first disengaged from its clutch and then the brake is applied. Thus,, there is avoided that unnecessary wear that inevitably ensues where power is permitted to act before the braking action is entirely 'at an The relation of the wedges 74 to.
